ABSTRACT:
A method for producing a profile specifying the correspondence relationship of values in different color spaces, includes a step of acquiring a first correspondence relationship that is a correspondence relationship of a plurality of ink amounts and color values, a step of acquiring a plurality of grid points that are a plurality of grid points in a predetermined color space and for which a relative relationship between the adjacent grid points is defined, a step of acquiring a second correspondence relationship that is a correspondence relationship of the plurality of grid points and color values, a step of acquiring a third correspondence relationship that is a correspondence relationship of the plurality of grid points and ink amounts based on the first correspondence relationship and the second correspondence relationship, and a step of producing a profile specifying the third correspondence relationship.
